Embodiment Construction

[0026] The present invention will be further described below in conjunction with drawings and embodiments.

[0027] Such as figure 1 As shown, the present invention includes a front cover assembly 1, a first middle body assembly 3, a second middle body assembly 4, a cylinder assembly 8, a push rod disc assembly and a piston assembly. The front cover assembly 1 is connected with the first middle body assembly 3 , the second middle body assembly 4 is connected with the cylinder block assembly 8 , and the first middle body assembly 3 and the second middle body assembly 4 are fixed by welding. A dustproof ring 19 is sheathed on the outer ring of the front cover assembly 1 .

[0028] A film 2 is provided in the first space formed by the front cover assembly 1 and the first middle body assembly 3, and the film 2 separates the first space into two chambers, respectively the chamber A of the push rod disc assembly and the chamber B of the service brake. The push rod disc assembly is...

Abstract

The invention discloses a brake air chamber with a self-locking type parking mechanism. The brake air chamber comprises a front cover assembly, a first middle body assembly, a second middle body assembly, a cylinder body assembly, a push rod disc assembly and a piston assembly; a leather membrane is arranged in first hollow formed by the front cover assembly and the first middle body assembly, thefirst space is divided into two cavities through the leather membrane, the two cavities are a push rod disc assembly cavity and a driving brake cavity, the push rod disc assembly is mounted in the push rod disc assembly cavity, the piston assembly is arranged in a second space formed by the second middle body assembly and the cylinder body assembly, a self-locking mechanism is arranged in the second space, and the piston assembly is arranged between the self-locking mechanism and the cylinder body assembly. Original energy storage strong springs are replaced, parking tasks are finished, safety of the brake air chamber is higher, and the service life is longer.

Description

technical field [0001] The invention relates to the field of automobile brake air chambers, in particular to a brake air chamber with a self-locking parking mechanism. Background technique [0002] At present, the brake air chambers of automobiles with parking function all adopt energy storage spring brake air chambers with both service brake functions and parking brake functions. During parking braking, the air pressure in the parking chamber is released through the parking valve, and the spring force of the energy storage spring acts on the push rod disc assembly through the piston assembly, and is transmitted to the brake to make the brake work and realize the parking brake. Therefore, the key component of the parking brake air chamber is the energy storage spring. Due to the frequent operation of the parking brake, the service life of the energy storage spring is limited. Once the energy storage spring fails, the parking brake will fail and cannot achieve parking. The e...
